温庄煤指标气体影响因素的灰色斜率关联度分析

Grey Slope Incidence Degree Analysis of Index Gases Influencing Factors for Wenzhuang Coal

摘要: 为了准确地找出实验条件中影响指标气体产生的主要因素,利用灰色斜率关联模型,分别计算了温庄煤各指标气体生成量与实验的初始温度、温升速率、干空气流量、煤样质量的斜率关联度。计算结果表明,初始温度是影响指标气体产生的关键因素,煤样质量和干空气流量次之,程序升温速率最小。

Abstract: In order to find accurately the principal factor that influencing index gases production under experimental conditions,formation amount of Wenzhuang coal index gases and the slope incidence degree of experimental initial temperature,temperature rising rate,dry air flow and coal quality are calculated.The results show that the initial temperature is regarded as the critical factor which affects the index gases producing,dry air flow rate and the weight of coal sample take the second place,and the temperature-programmed rate has the least effects to the index gases producing.
